Patented Apr. 18, 1939 UNITED STATES PATENT OFFICE 7 Claims.

My invention relates to hair waving devices, for producing permanent waves or the like.

An important object of the invention is to provide a device holding exothermic material, for heating the lock of hair wound upon the curler.

A further object of the invention is to provide a heating device of the above mentioned character which may be quickly and conveniently applied to and removed from the curler having the lock of hair wound thereon.

A further object of the invention is to provide a heater of the above mentioned character so constructed that the exothermic material may be held therein, without liability of directly contacting with the wound lock of hair.

A further object of the invention is to provide a heater of the above mentioned character having a recess for receiving the exothermic material, and an element to close the recess and to serve as means to hold the jaws of the heating device in the closed position.

A further object of the invention is to provide a heater of the above mentioned character, which is in the nature of a clamp, having opposed jaws, 35 which may be readily applied to and removed from the curler having the lock of hair wound thereon.

Other objects and advantages of the invention I will be apparent during the course of the follow- :0 ing description.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 2 is a perspective view of the device removed,

Figure 4 is a plan view of the same,

Figure 5 is a transverse section taken on line 55 of Figure 4, and,

; Figure 6 is a longitudinal section taken on line 6-6 of Figure 5.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral l0 designates a clamp which is arranged next to the scalp and holds a lock of the hair II to be waved, and this lock is wound about a curler I 2, in the croquignole manner, or in any other suitable manner. A chemical pad or shield I3 is usually placed upon the wound lock. As is well known in the art of permanent waving, the lock of hair prior to or while being wound upon the curler I2, is subjected to a chemical or softening solution, and the pad or shield I3 may be saturated with the solution. The wound lock is placed under suitable tension and maintained under this tension while it is subjected to heat, in the presence of the softening solution, which eifects the waving.

My invention resides principally in a heater, in the nature of a clamp, using exothermic mateo rial. This heater comprises a pair of opposed jaws I4, which are hollow and embody inner circularly curved walls I5, inner bottom walls l6 and outer side walls H. The walls I6 and I1 are preferably straight. The jaws further comprise end walls 8. The two assembled opposed jaws produce a chamber, the top of which is open. The inner curved walls I5 are provided with apertured knuckles l9 and 20, arranged to interfit and receive a pintle 2!, pivotally connecting them. These knuckles snugly interflt and form a tight joint.

At corresponding ends, the outer walls I! have upwardly projecting finger grips or extensions 22, to be moved inwardly, to cause the jaws I4 to spread.

The assembled jaws, Figure 5, produce an inverted generally U-shaped chamber 23. The top of this chamber is adapted to be closed by a lid or cover 24, for insertion therein, having an extension to enter the slot 26, and a resilient catch 21, preferably stamped therefrom, and provided with a lip or flange 28 extending over the side of the heater. The resilient catch may be provided with a lug 29 to enter a recess 30 formed in the adjacent side wall I1,

Adapted for insertion within the inverted generally U-shaped chamber, is a pad 3|, containing the exothermic material. This pad is adapted to be bent into a form which is U-shaped in cross section for insertion within the chamber 23.

The operation of the apparatus is as follows:

The clamp I0 is applied to the look I I in the usual manner, and the lock wound upon the curler I2, with the softening solution applied thereto, and the pad or shield I3 arranged upon the wound lock. The jaws l4 of the heater are now spread, by pressing the finger grips 22 inwardly and are arranged upon the opposite sides of the wound lock, subsequently to which the jaws are swung inwardly to engage with the pad or shield I3. The pad 3| containing the exothermic material is now inserted in the chamber 23, and water or moisture applied thereto, and the cover .swung outwardly so that the heater may be 24 inserted within the upper end of the chamber, as indicated, serving to close the upper end of the chamber and to also hold the jaws l4 in the closed position. The inner walls ii of these jaws now frictionally engage the pad or shield l3, and the wound lock and curler are held against turning movement, by such frictional engagement, or by any other suitable means, so that the lock may be placed under suitable tension and maintained under this tension, during the curling period. After the hair has been subjected to the heat treatment, for a suitable length of time, the cover 24 is removed and the jaws l4 separated from the wound lock on the curler. The pad 3| may then be readily removed. Attention is called to the fact that the cavities of the hollow jaws extend throughout substantially the entire longitudinal and transverse dimensions of the jaws. The pad 3| containing the exothermic material fits within the chamber 23 formed by these assembled cavities, and this pad also extends throughout substantially the longitudinal and transverse dimensions of the jaws and their cavities. The inner walls l5 of the jaws substantially encircle the curler and lock of hair wound thereon, whereby a substantially uniform heat treatment is applied to the wound hair throughout substantially its entire circumference.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts, may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A heater to be applied to a lock wound upon a curler, said heater comprising a pair of opposed hollow jaws, having circular curved inner walls adapted to extend substantially around the curler, the hollow jaws having cavities extending throughout substantially their entire vertical dimensions, the cavities, when the jaws are assembled, forming an inverted generally U-shaped chamber, means to adjustably connect the assembled jaws, a pad containing exothermic material for insertion within the chamber, and means for retaining the jaws in the closed position.

2. A heater to be applied to a lock wound upon a curler and attached to the head, said heater comprising a pair of opposed hollow jaws, each hollow jaw having inner and outer spaced walls forming a cavity, means for adjustably connecting the hollow jaws so that they may assume inner positions, the cavities, when the jaws are in the closed position forming a chamber which is generally U-shaped in cross-section and adapted to receive a pad containing exothermic material, the pad extending into the cavities.

3. A heater to be applied to a lock wound upon a curler and attached to the head, said heater comprising a pair of opposed hollow jaws, each jaw including inner and outer spaced walls forming a cavity, means for pivotally connecting the hollow jaws so that they may be moved to a closed position, the cavities, when the hollow jaws are in the closed position forming a chamber which is generally U-shaped in cross-section and adapted to receive a pad containing exothermic material, the pad extending into the cavities, and means for holding the hollow jaws in the closed position.

4.
